SUMMARY
On March 26, 2019, Council approved a PSA with SDI for the final design services and construction support for the La Vista Park Project in an amount not-to-exceed $515,000. The design phase for this project is conducted in two phases. Phase 1 involved preparation of 30% final design of the project. The 30% design was used to define the project scope and to revise the CEQA review and addendum for the addition of a 20-acre Caltrans Route 238 parcel to the project. The CEQA review and addendum was completed and presented to Council on September 28, 2021. Council authorized staff to proceed with Phase 2 design work, which involves finalizing the design and preparing construction documents.
An existing wetland area and man-made well was identified on the 20-acre Caltrans Route 238 parcel. The existing well was sealed to determine if the wetland was being fed by a man-made source. Wetland areas fed by man-made wells are not protected wetlands. The man-made well was found to have contributed to the creation of most of the wetland area. A small remaining area was determined to be a natural wetland area. The design of the park was revised to avoid any disturbance to this existing wetland area. A revision to the landslide stability plan was then required to avoid any repairs that would directly impact the small existing wetland area.
The contract amendment requested for the SDI agreement is for additional costs for design verification, grading revisions, exhibit preparation, topographic surveying, meetings, and coordination of the CEQA review and findings. In addition, slope stabilization construction documents will be prepared to expedite the construction of the proposed slope stabilization keyway. This approach allows work to begin while the overall park construction documents are being finalized. Staff requests approval of the attached resolution to amend the SDI PSA is in an amount of $122,975 for a total contract not-to-exceed amount of $637,975.
On March 26, 2019, Council approved a PSA with Langan for the geotechnical investigation and report for the La Vista Park Project in an amount not-to-exceed $220,000. On May 19, 2020, Council approved an amendment to the Langan PSA to increase the agreement to an amount not-to-exceed $293,400. This contract amendment is for additional work to revise the slope stability analysis, review revised grading plans and slope stability keyway plans, meetings, coordination, and construction monitoring for the slope stability keyway construction. Staff requests approval of the attached resolution to amend the Langan PSA in an amount of $200,026 for a total contract not-to-exceed amount of $493,426.
